Question

What does x=? I'm really not sure about this.

Answer 1

X= 9
Because all you have to do is divide one of the bigger sides by one of the smaller sides on the other shape and you will get the scale factor of 1.8 and when you take 1.8 and divide it by 5 you would get 9

Answer 2

9

Explanation:

For this, we need to know the scale factor first. We can do that by looking at a same side of the two shapes.

CD = 2 and ML = 3.6

3.6 / 2 = 1.8

just to confirm, let's take MN = 7.2 and DE = 4

7.2 / 4 = 1.8

So now we know the scale factor is 1.8

Now to figure out x, we just need to use BA = 5

and because the scale factor is 1.8

so we just need to do: 5 * 1.8 = 9
